Seeking help with Klaus sulfur recovery design (undergraduate graduation project)
Thread Content
This post was last edited by liaifeng on 2018-7-29 at 15:40. Our graduation project requires us to carry out a process design for Claus sulfur recovery. Super Claus separation process: three stages of conversion, two stages of conventional Claus process, and the final stage is selective oxidation. No treatment for exhaust combustion is designed. The composition of the acidic gas is 35% hydrogen sulfide, 55.5% carbon dioxide, 5.5% nitrogen, 3.5% methane, and 1% inert gases such as helium. After all, I’m a beginner... I don’t know much about design. I have some questions I’d like to ask the experts on this forum. 1. For combustion furnaces, there are too many reactions taking place inside – what kinds of reactions are they? How are the material balance and heat balance calculated for a combustion furnace? Can it be simplified? 2. Is elemental sulfur formed in the combustion furnace using the shunt method? If not, how much air or oxygen needs to be supplied? 3. If elemental sulfur is present in the combustion furnace, what should be the conversion rate of hydrogen sulfide in the first conversion furnace? And if no elemental sulfur is present, what should be the conversion rate of hydrogen sulfide in the first conversion furnace? 4. What side reactions occur in each section of the conversion furnace downstream of the combustion furnace? Thank you to all the experts{:3_64:}
I suggest you start by reading a book on sulfur recovery. This type of design requires the collaboration of a team of thirty to forty people; even just the process itself takes a long time to implement
Perhaps the content on the sulfur section of the coalification area in the forum will be helpful to you.
This is much better than simply asking for design documents directly. However, it’s still a general question that makes it difficult to address or engage in discussion. It is recommended that the original poster raise specific questions one by one for discussion --------------------------------------------------
Good suggestion; hurry up with the formalization process. Once it’s done, you’ll be able to start working right away
I have no idea what our teacher is thinking.
You don’t even know the simplest reactions; you should take some time to study the relevant materials first. This isn’t something you can handle on your own. First, you need to develop a material balance – that’s part of the process design – and only after that can you move on to equipment design. If you’re capable of doing things on your own, then you’re at an expert level.
